What are loose bodies in the shoulder?
The glenohumeral joint, one of the three main shoulder joints, is the articulation between the head of the humerus (upper arm bone) and the glenoid socket of the scapula (shoulder blade). Repetitive use of this shoulder (throwing, pitching, serving) or shoulder trauma (dislocations, falls) can cause the cartilaginous tissue that lines the end of these bone to deteriorate. This deterioration can generate small free pieces of cartilage or bone that “float” in the intra-articular (joint) space. These fragments can become lodged within the joint space and can cause mechanical symptoms in the shoulder (locking, catching). Some individuals may experience a sharp and sudden pain in the shoulder that can make joint movement difficult. Dr. Riley J. Williams, orthopedic shoulder specialist serving patients in Manhattan, New York City, and the surrounding New York boroughs, has the knowledge and understanding, as well as substantial experience, in treating patients who have experienced loose bodies in the shoulder.
